John Gill Commentary Genesis 41:24

"and the thin ears swallowed up the seven good ears: and I told it unto the magicians; but there was none that could declare it to me." — Genesis 41:24 (ASV)

And the thin ears devoured the seven good ears (See Gill on Genesis 41:7); and I told [this] to the magicians ; but [there was] none that could declare [it] to me ; the meaning of it; what all this should signify or portend.
